Tantalum-doped tin oxide thin films using hollow cathode gas flow sputtering technology.

SnO and tantalum doped SnO (TTO) thin films were prepared using reactive hollow cathode gas flow sputtering (GFS) on glass substrates. An in-situ heating process under vacuum preceded the sputtering. The resistivity of the tin oxide films was reduced to a remarkable low of 2.

The fluorescence mKate2 labeling as a visualizing system for monitoring small extracellular vesicles.

Small extracellular vesicles (sEVs) are nanosized vesicles enclosed in a lipid membrane released by nearly all cell types. sEVs have been considered as reliable biomarkers for diagnostics and effective carriers. Despite the clear importance of sEV functionality, sEV research faces challenges imposed by the small size and precise imaging of sEVs.

Effects of FGF2/FGFR1 Pathway on Expression of A1 Astrocytes After Infrasound Exposure.

Two types of reactive astrocytes, A1 and A2 astrocytes, are induced following neuroinflammation and ischemia. In this study, we evaluated the effects of the fibroblast growth factor (FGF)2/FGF receptor (FGFR)1 pathway on A1 and A2 astrocytes in the rat hippocampus using double-labeling immunofluorescence following infrasound exposure. A1 astrocytes were induced in the CA1 region of the hippocampus after exposure to infrasound for 3 days.

Che-1 inhibits oxygen-glucose deprivation/reoxygenation-induced neuronal apoptosis associated with inhibition of the p53-mediated proapoptotic signaling pathway.

Accumulating evidence suggests that Che-1 is a strong antiapoptotic protein and can protect cells against various insults. However, whether Che-1 is involved in the protection of neurons against cerebral ischemia/reperfusion injury remains unclear. In this study, we aimed to investigate the potential role of Che-1 in regulating cerebral ischemia/reperfusion injury-induced neuronal injury using the oxygen-glucose deprivation and reoxygenation (OGD/R) model in vitro.

Thermophilic production of polyhydroxyalkanoates by a novel Aneurinibacillus strain isolated from Gudao oilfield, China.

Polyhydroxyalkanoates (PHAs) are usually biosynthesized using mesophilic strains, but the fermentation processes often suffer from bacterial contamination. This work reports the screening of thermophilic bacteria capable of producing PHAs under elevated temperatures to reduce the contamination risk. Strain XH2 was isolated from an oilfield and identified as Aneurinibacillus sp.

Thermophilic fermentation of acetoin and 2,3-butanediol by a novel Geobacillus strain.

Background: Acetoin and 2,3-butanediol are two important biorefinery platform chemicals. They are currently fermented below 40°C using mesophilic strains, but the processes often suffer from bacterial contamination.

Results: This work reports the isolation and identification of a novel aerobic Geobacillus strain XT15 capable of producing both of these chemicals under elevated temperatures, thus reducing the risk of bacterial contamination.

A novel 2,3-xylenol-utilizing Pseudomonas isolate capable of degrading multiple phenolic compounds.

This work characterized a novel 2,3-xylenol-utilizing Pseudomonas isolate XQ23. From 16S rRNA phylogenetic analysis, XQ23 was found to be a member of the Pseudomonas putida group. Most of its physiological characteristics also shared similarities to P.
